NAME THAT FOSSIL:
This fossil forms when sediments bury an organism and the sediments change into rock. Then, the organism decays leaving a cavity (hollow area) in the shape of the organism.
mold fossil
cast fossil
preserved fossil
trace fossils
NAME THAT FOSSIL:
This fossil forms when minerals soak into the buried remains, replacing the remains, and changing them into rock.
carbonized film fossil
cast fossil
preserved fossil
petrified fossils
NAME THAT FOSSIL:
This fossil forms when a mold is filled with sand or mud that hardens into the shape of the organism.
mold fossil

NAME THAT FOSSIL:
This fossil forms when the mud or sand hardens to stone where evidence of an organism is left behind such as footprints, coprolites (feces), egg shells, gastroliths (stomach stones), regurgitaliths (vomit), nests, trails, burrows, etc...)
mold fossil
cast fossil
trace fossil
carbonized film fossil
NAME THAT FOSSIL:
This fossil forms when organisms are pressed between layers of soft mud or clay that hardens squeezing almost all the decaying organism away leaving the carbon imprint in the rock.
preserved fossil
petrified fossil
trace fossil
